Cypress is a popular JavaScript-based testing framework used for end-to-end testing in modern web applications. If you are preparing for a job interview, knowing Cypress inside out can give you an edge. This guide covers the top 20 Cypress interview questions and answers for freshers as well as experienced candidates.
So, let’s begin!
Fun Fact: In 2025, over 4,164 companies worldwide used Cypress for testing.
Cypress Interview Questions for Freshers
Here is a list of common Cypress interview questions and answers for freshers:
- What is Cypress, and how is it different from Selenium?
Cypress is a JavaScript-based testing framework used for end-to-end testing of web applications. Unlike Selenium, which supports multiple languages, Cypress runs directly in the browser and operates within the same run loop as the application. This makes it faster and more reliable for UI testing. It also eliminates the need for WebDriver, simplifying setup and execution.
- How does Cypress handle asynchronous operations in tests?
Cypress automatically waits for commands and assertions to complete before moving to the next step. It does not require explicit waits or callbacks. Instead, it uses a built-in retry mechanism to check for elements dynamically.
For example, cy.get(‘button’).click() waits for the button to appear before clicking it.
- What are some key features of Cypress?
Cypress offers fast execution, built-in retry logic, automatic waiting, real-time reloading, network request interception, and a time-travel debugging tool. It provides a simple API with powerful commands to interact with elements and verify application behaviour.
- How do you install and set up Cypress in a project?
Cypress can be installed using npm:
npm install cypress –save-dev
To open Cypress, run:
npx cypress open
This launches the Cypress Test Runner, where tests can be created inside the cypress/integration folder.

Cypress Interview Questions for Experienced
Here are common Cypress interview questions and answers for experienced candidates:
- How does Cypress handle API testing, and how do you stub network requests?
Cypress provides cy.request() for making API calls and cy.intercept() to stub network requests.
For example, to stub a response:
cy.intercept(‘GET’, ‘/api/users’, { fixture: ‘users.json’ }).as(‘getUsers’);
This replaces the actual API response with predefined data from users.json.

- What are Cypress fixtures, and how do you use them?
Fixtures store static test data in JSON files. They help mock responses in tests.
To use a fixture:
cy.fixture(‘users’).then((data) => {
cy.get(‘#username’).type(data.username);
});
- How do you handle authentication and session management in Cypress tests?
Cypress supports session management using cy.session(). Alternatively, authentication can be done via API:
cy.request(‘POST’, ‘/login’, { username: ‘test’, password: ‘1234’ }).then((resp) => {
cy.setCookie(‘auth_token’, resp.body.token);
});
This avoids logging in via UI on every test.
- What are some limitations of Cypress, and how do you work around them?
Cypress does not support multiple browser tabs or native mobile testing. Workarounds include simulating new tabs using target=”_self” or using other tools for mobile testing. It also struggles with iframe interactions, which can be handled using cy.iframe() from plugins.
- Can you describe a challenging Cypress testing scenario you faced and how you resolved it?
This is one of the most commonly asked Cypress interview questions for 2 years experienced candidates.
“In one project, I had to test an application with dynamic pop-ups that disappeared unpredictably. Cypress was failing because elements weren’t available in time. To fix this, I used cy.intercept() to wait for the pop-up request and applied .should(‘be.visible’) before interacting with elements. This made the tests stable across different runs.”

Cypress Automation Interview Questions
Let’s go through frequently asked Cypress automation interview questions and answers:
- How do you automate form submissions in Cypress?
Cypress automates form submissions using cy.get() and .type(), followed by .submit():
cy.get(‘#name’).type(‘John Doe’);
cy.get(‘#email’).type(‘john@example.com’);
cy.get(‘form’).submit();
It automatically waits for elements before typing or clicking.
- How does Cypress handle retries in test execution?
Cypress retries commands like cy.get() and assertions automatically. If an element isn’t found immediately, Cypress keeps checking until the timeout is reached. No extra retry logic is needed.

Cypress Testing Interview Questions
You might also come across interview questions on Cypress testing like these:
- How do you debug failing Cypress tests?
Cypress provides detailed error messages, screenshots, and videos of test failures. The cy.pause() command can be used for debugging, and cy.log() helps track values inside tests. Running tests with cypress open allows step-by-step debugging in the browser.
- What are Cypress custom commands, and how do you create one?
Custom commands simplify repetitive actions. They are defined in cypress/support/commands.js:
Cypress.Commands.add(‘login’, (username, password) => {
cy.get(‘#username’).type(username);
cy.get(‘#password’).type(password);
cy.get(‘button’).click();
});
Then used in tests:
cy.login(‘testuser’, ‘password123’);
Cypress JavaScript Interview Questions
- How does Cypress handle promises and async behaviour in JavaScript?
Cypress commands are inherently asynchronous but do not return promises. Instead of .then(), Cypress chains commands using implicit waiting. Example:
cy.get(‘#element’).should(‘be.visible’);
No need for await or .then() unless accessing command results.
- What is the role of cy.wrap() in Cypress, and when should you use it?
cy.wrap() is used to work with non-Cypress values inside tests.
Example:
cy.wrap({ name: ‘John’ }).its(‘name’).should(‘eq’, ‘John’);
This makes external values behave like Cypress commands.
- How do you organise and structure Cypress test files in a large project?
You might also come across Cypress framework interview questions like this one.
A well-structured project has separate folders for integration (tests), fixtures (test data), support (custom commands), and plugins. Tests are grouped by feature or module for maintainability.

Cypress Coding Interview Questions
- Write a Cypress test to validate a login functionality with incorrect credentials.
cy.visit(‘/login’);
cy.get(‘#username’).type(‘wrongUser’);
cy.get(‘#password’).type(‘wrongPass’);
cy.get(‘button’).click();
cy.contains(‘Invalid credentials’).should(‘be.visible’);
- How would you write a custom Cypress command to check if an element is visible?
Cypress.Commands.add(‘isVisible’, (selector) => {
cy.get(selector).should(‘be.visible’);
});
- Write a test script in Cypress to validate dynamic dropdown selections.
cy.get(‘#dropdown’).click();
cy.contains(‘Option 2’).click();
cy.get(‘#dropdown’).should(‘contain’, ‘Option 2’);
- How do you write a Cypress test to handle file uploads?
cy.get(‘input[type=”file”]’).attachFile(‘sample.pdf’);
cy.get(‘#upload-status’).should(‘contain’, ‘Upload successful’);
